OK - this may be a st00pid question, but I'm wanting to get an idea what's going on even before I bother to sink $15 or whatever into the 10-year-old computer I'm using for a fileserver on my home LAN...

Basically, sometime on the overnight, my Ethernet connection to my server stopped responding. Rebooting, running from a recovery disk, etc...none of them can get my network up.

I'm getting a PCI bus error 8000 & 8010 all over the place on boot, when I do lspci, it just shows my ethernet card as an "unidentified pci card" that is by D-Link, which is the manufacturer.

This machine is old enough that it certainly is within the realm of possibility that the board is fried, but it could also very possibly be the ethernet card, which is only 3 years old.

Any quick & dirty way to tell without going to the headache of swapping out the card?

Thanks!
